This metal absorber was coated by using nano- graphite and ZnO based absorptive solution so as to have Figure 1 XRD pattern of nano-graphite based absorptive coating The thermal enhancement on solar absorber was measured periodically in diverse meteorological conditions in outdoor atmospheres. It was...
aThe XRD pattern of NG-1000 shown in Supplementary Fig. S2 has a broad peak at ∼26.2°, corresponding to an inter-layer spacing of 0.340 nm that is close to 0.335 nm for graphite. 在补充显示的NG-1000的XRD样式。 S2有一个宽广的峰顶在∼26.2°,对应于是近0.335毫微米为石墨0.340毫微米的...
Overall, the peak shift in the XRD pattern of carbon material XRD002 can be attributed to impurities, changes in crystalline structure, size and morphology effects, as well as experimental and instrumental factors. 中文回答: 碳材料XRD002的XRD图谱中的峰偏移可能有几个原因。一个可能的原因是样品中存...
XRD pattern of the coal shows that it is amorphous in nature. Function of Radial Distribution Analysis (FRDA) indicates that coal is lignite in type and there is no evidence of graphite-like structure. The first maximum in the G( r ) plot of FRDA at r...
Once an X-ray scattering or diffraction pattern has been measured. It needs to be analyzed. Analysis of X-ray diffraction and X-ray scattering data can be very complex. To make this easier for the user, a variety of XRD software packages exist to support all the different types of measure...
钱崇梁,周桂芝,黄启忠 (中南大学粉末冶金国家重点实验室,湖南长沙 410083)摘要:研究了用X 射线衍射(XRD )测定炭素材料石墨化度的原理和方法,指出其本质是精确测定炭石墨六方晶格的C 轴点阵常数值,为此,用高纯硅粉作内标以校准测量误差.为提高测量精度,选用高角度的C (004)-S i (311)衍射线对;当试样的石墨化...
1(a). The results show that the XRD pattern of Li4.4Sn alloy can be indexed to a mixture of three phases, a cubic phase in the F23 space group (JCPDS No. 00-018-0753)(Hightower et al., 2000), crystalline Conclusions Tin monoxide (SnO) was successfully prepared via a simple one ...
XRD pattern was similar to the real version in general, a complete coincidence would not be possible. The object of our XRD pattern simulation was to develop an XRD pattern that appeared like those normally measured by ordinary lab XRD machines. For robustness, it is necessary to test the ...
23、C/ C composite, and so the profile of diffraction pattern was not symmetrical. So multiple -peak separation should be executed, and the separated peaks could be used to calculate graphitization degree directly. In this condition, therec s no need for the double -peak separation. The integ...
On the basis of X-ray, studies of coal reported by many researchers [12–14] show that the X-ray diffraction pattern of coal resembles a very blurred graphite pattern similar to that obtained with activated carbons and carbon black. Of note, Hirsch [15], Watanabe et al. [16], and ...
